To all whom t may concern.-

Be it known that I, ALBERT J. LonPsINGER, -a citizen of the UnitedStates, residing at Edgewood, vin the county of Providence and State ofRhode Island, have invented certain new and useul Improvements in Sprin`kler Heads, specification. The invention relates to improvements 1nsprinkler-heads, being a division of the subfject matter disclosed in myapphcation for of which the following is a i patent, Serial No. 221,850,filed March 11,

1918. It is intended that the present atent shall cover by suitableexpression in t e appended claims, whatever features of patentablenovelty exist in the inventlon herein fdisclosed. Said invention isdesigned primarily for use in connection with that class ofsprinkler-heads known in the art as open rinklers which are designed andadapted gir use upon the exterior of ybuildings to direct a stream ofwater a ainst the exterior "wall of the Ibuilding and t rough or againstthe windows thereof. v

In sprinkler-heads of this character as heretofore produced, a deflectorhas been employed which has a flat surface arranged opposite the outletopening and at right angles to the axis thereof. The great objection tothe use of a dellector of this charmeter resides in the fact that thestream of water issuing from the outlet opening is not only broken upafter it issues from the nozzle and when it strikes the surface of thedelector which is arranged at right angles to the axis of the outletopening, but the velocity and ener of said stream at the same time isgreat y reduced, which in turn reduces the area of distribution.

The principal object of the present invention is to overcome the aboveobjections and to rovide a s rinkler-head of this type with a dbilectoro such character as not to decrease the velocity of the stream of waterto as great an extent as would a flat deilector, and also to produce awider and better distribution of said stream against the wall of thebuilding rotected.

A further object o the invention consists in providing the sprinklerwith a deflector of the above character which is arranged and adapted toreceive and direct 'the stream 7, dated December 19, 1922i.

Application for reissue of water tangentially to the inner surface ofsaid deflector.

A further object of the invention consists 1n providing the sprinklerwith a. deflector of the above character which has a continuous curvedsurface extending from the sprinkler nozzle and partially surroundingthe outlet opening for directing and controlling thellow of water fromthe moment it leaves said nozzle.

It is a result of the invention that the relative amount of waterprojected from various segments of the deector can be controlled so thatwhile the whole is projected to one side of a plane through the axis ofthe nozzle, so as'to strike an adjacent plane surface, such as theoutside Wall of a building, the distribution of liow may be either madeapproximately uniform from all parts of the delivery edge of thedelector, or approximatel uniform toward all the parts of the wal whichit is to strike, or may be otherwise controlled, either to concentrate aconsiderable liow at some particular region or regions, or to avoidconcentration. This is accomplished by the provision 'of a ridge orraised part of the surface of the detlector over which the water Hows,which ridge causes the water, which in the absence of the ridge wouldflow out straight in the middle in much larger volume, to be distributedsomewhat transversely from the middle of the deflecting surface and to'low out more toward one side or the other, thus giving both a'reduction of central flow and an increased throw toward each side. Insuch a case'more water is supplied to the sides, where a given angle ofthe deflector has to supply a greater linear length of wall, because ofthe Obliquity with which it strikes; and the throw in that direction isincreased both in quantity and in force, which means throwing to agreater distance.

To these ends the invention consists in the novel construction andarrangement of parts hereinafter described and more particularly setforth in the claims.

In describing the invention in detail, reference will be had to theaccompanying drawings in which,

Figure 1 is a front elevation of a sprinklerhead embodying my novelconstruction.

' It will also Figure 2 is a vertical sectional view on line :uf-fp'Figure 1.

Figure is' n transverse line y-/y Figure 1.

Referring to the drawings 1 represents a tubular nozzle having externalthreads 2 for attachment to a water supply system and the usual outletopening 3. Formed integral with, or secured to, the nozzle 1 is adeflector 4 which-coin rises a body ortion 5 extending g e y parallel mt e axis of the nozzle 1 and located adjacent to and curved transverselyso as to artially surround the outlet opening 3. y'lille outer free endportion 6 of the delector 4 extends laterally from the body portion 5,as shown in Figure 2, The interior Sul-flux of Seid defleotor 4 iscurved both transversely and longitudinally and the ctldprton 6 itsprovided upon its interior with `tuno eontinuious curved surfaees 7 and8, having e, raised rib 9 at the point of interseetiou of said curvedsurfmes, as shown in Fi re 1.

Vith the above construetion it will be seen sectional View on 'that thestream oi water lowing from the outlet opening will be directed alongthe curved body portion 5 of the deileoter 4 and flow tangentially alongthe continuous curved inner suefaee of said deieetor 4 and bedistributed imm the outer :free end 6 of said distributor tangentiallyto the plane of dirihution. It will also he seen that a portion of thestream issuing from the outlet :Toning will be dincted against theraised b 9 and be distributed transversely as well as from the curvedsurfaces 7 an 8.

be seen that the eontinuous interior of the disin the d mall- .emvedsurfaces upon the triinltor will cause a gradual change direction of Hawof the water in sue ner lnennt to materially reduce the velocity,

or ener thereof @nd also will result in the wider distribution of thestream. Inasmueh as the does not extend'tothe delivery edge of e tor,water is diseharged from allvparts of the edge of the defleetor in a sif continuous diverging sheet.

It wi also be seen that by changing the euroatune of the outer end 6 ofthe distributn'r die direction of distribution can likewise be changedso that the Water can be distributed therefrom either at right angles tothe axis of the nozzle or at an acute angle or an obtuse angle thereto.

I .claim as my invention:

l, A sprinkle-r head, comprising a nozzle combined with a deflector, thesaid deflector being arranged starting in substantially the initialdirection of the jet and curving with smooth non-spraying surfacethrough substantially a right angle therefrom to a delivery ed espreading throughawideangle, whereby t e momentum of the water i'lattensthe current against the dector inw Spreading shed form combined with arear and side plate limitlng the delivery to a spread not exceeding tworight angles; .said dleetor having in its dellecting tending from saidveel' plate out toward Said edge, and ending within the eurnent, Wherebywater has access to flow from substantially all of said edge, said ridgebeing arranged and adapted to influence the lateral distribution ofwater over the surfaoe of the defieetor. y

2.
